Object Mesh is Disappearing in Edit Mode but is not Hidden
Let's try the most simple stuff, see if you haven't accidentally hide all, so in edit mode press Alt+H.
Other simple stuff is to press A and then press G and move around (if the mesh is in any case behind other object), you then must see a lot of orange points going around.
If that does not resolve the problem, in object mode set the Origin to the Geometry and in edit mode press Shift+S and (cursor to selection) and in view 3D cursor you can see the co-ordinates where the cursor goes, try to locate that and you must see the mesh, (don't press selection to cursor cause all your mesh will be compressed in one point)
If that does not solve, try to look in Object properties&gt; viewport display &gt; display as &gt; and set to Textured or Solid.
If you can't see still, see if you are in preview or render mode so it could be a transparent texture issue so you must adjust your UV maps.
Feel free to give me a feedback if case that none of them not solve the problem.
